Introduction
Scheduled 168h of more MD time in 2011: 120h in MD block #4. 48h in floating MD‘s (scheduled during physics run).
We could have scheduled another 230h (see list) and more (in your requests that we already reduced)...
Not everything can be done! We will also have MD time in 2012! Will ask for new requests
for next year, which should take into account results achieved in 2011.
All this depends on your input to us!

Discussion
What should NOT be done and what MUST still be done in 2011? Scheduled 168h of more MD time in 2011. We could have scheduled another 230h (see list) and more (in your
requests that we already reduced)...
R. Assmann03/10/2011
Thank you...
